I've found that I can move around easier within Unity, in the scene view, the tabbed windows, etc. Probably just a by product of using it on a regular basis. There were two trigger colliders, one for the bullets hitting the enemy, and another for when the enemy grabs out player. After each of these tutorials, I am wow-ed at how easily it is to get things to a playable state. I know that we are mainly dealing with pre-generated assets, but there is a lot of work that has already been done for us game-wise that we just have to learn how to tap into in order to get things working.
Stuff I learned
I am understanding State machines for the animations better. I know that they don't do anything on their own, but are things that are triggered when other things happen.
Stuff I didn't understand
It's not that I didn't understand this, but it's more of a realization that I need to understand it fully because it's coming up so frequently is "Transform". So yea, get on that!
